Cyclical method of producing high-purity nitrogen and optionally a high-purity hydrocarbon from a feedstock containing nitrogen and a hydrocarbon

a technology of high-purity hydrocarbons and feedstocks, which is applied in the direction of separation processes, chemical/physical/physico-chemical processes, and dispersed particle separation, etc., can solve the problems of high cost of methods, low yield, and often inability to recycle nitrogen and hydrocarbons in the process

Abstract

The invention relates to a cyclical method for producing a nitrogen fraction, the purity of which is greater than or equal to 95 mol %, and a hydrocarbon-enriched fraction from a filler containing nitrogen and a hydrocarbon, said method using a specific class of porous hybrid solids as an adsorbent in a pressure-swing adsorption (PSA) process. The invention also relates to equipment for implementing said method.

Description

RELATED APPLICATIONS

[0001] The present application is a National Phase entry of PCT Application No. PCT / EP2012 / 075676, filed Dec. 14, 2012, which claims priority from U.S. Patent Application No. 61 / 710,333, filed Oct. 5, 2012, said applications being hereby incorporated by reference herein in their entirety.FIELD OF THE INVENTION

[0002] The present invention relates to a cyclical process for the production of a nitrogen fraction with a purity of greater than or equal to 95 mol % (2), on the one hand, and of a fraction enriched in hydrocarbon (3), on the other hand, from a feedstock (1) comprising nitrogen and a hydrocarbon, and also to an installation for the implementation of this process.BACKGROUND OF THE INVENTION

[0003] There exist many processes in the energy industry, the refining industry or the petrochemical industry during which a mixture of nitrogen and hydrocarbon(s) is formed. For example, during the production of polypropylene from propylene, nitrogen is used to purify the p...
